Chapter 5 Provisioning

Update Profiles and Firmware

Cisco conference phones support secure remote provisioning (configuration) and firmware upgrades. An
unprovisioned phone can receive an encrypted profile specifically targeted for that device without
requiring an explicit key by using a secure first-time provisioning mechanism using SSL functionality.
User intervention is not required to initiate or complete a profile update or firmware upgrade. If
intermediate upgrades are required to reach a future upgrade state from an older release, the Cisco IP
phone upgrade logic is capable of automating multi-stage upgrades. A profile resync is only attempted
when the Cisco IP phone is idle, because this might trigger a software reboot and disconnect a call.
General purpose parameters manage the provisioning process. Each Cisco IP phone can be configured
to periodically contact a normal provisioning server (NPS). Communication with the NPS does not
require the use of a secure protocol because the updated profile is encrypted by a shared secret key. The
NPS can be a standard TFTP, HTTP or HTTPS server with client certificates.
The administrator can upgrade, reboot, restart, or resync Cisco IP phones by using the phone web user
interface. The administrator can also perform these tasks by using a SIP notify message.
Configuration profiles are generated by using common, open-source tools that integrate with service
provider provisioning systems. (Provisioning is described in detail in the Cisco Unified IP Conference
Phone 8831 for Third-Party Call Control Provisioning Guide.)

Allow and Configure Profile Updates

The profile updates can be allowed at specified intervals. Updated profiles are sent from a server to the
phone by using TFTP, HTTP, or HTTPS.
To configure a profile update:
Step 1 Click Admin Login > advanced > Voice > Provisioning.
Under Configuration Profile in the Provision Enable field, choose Yes.
Step 2
Enter the parameters defined in the table:
Step 3
Parameter
Provision Enable
Resync On Reset
Resync Random Delay
Resync At (HHmm)
Description
Allows or denies resync actions. Defaults to Yes.
The device performs a resync operation after power-up and after each
upgrade attempt when set to Yes.
A random delay following the boot-up sequence before performing the
reset, specified in seconds. In a pool of IP Telephony devices that are
scheduled to simultaneously powered up, this introduces a spread in the
times at which each unit sends a resync request to the provisioning
server. This feature can be useful in a large residential deployment, in
the case of a regional power failures.
Time in 24-hour format (hhmm) to resync the device. When this
parameter is provisioned, the Resync Periodic parameter is ignored.
Default is empty.
